Sigmoidscopy is thought to be one of the basest and most essential tools for evaluation of colorectal patient because it could be performed in an out patient clinic with only minimal bowel preparation. AIM: The aim of this study was to assess the patient's best position for sigmoidoscopy. MATERIALS AND METHODS: Between March 4, 1997 and April 18, 1997, all patients who visited the colorectal clinic at the Dept. of Surgery, Korea Veterans Hospital were alternately underwent sigmoidoscopy in these four different positions: supine(S), left lateral(L), right lateral(R), and jack-knife(J). Sigmoidocopy was routinely performed for all patients who had lower gastrointestinal problems and was done by two well traind surgeons who had performed more than 100 sigmoidoscopies previously to this study, The patients who could not be tolerate insertion of the total length (60 cm) of the sigmoidoscope due to poor bowel preparation and/or complete obstruction by a mass were excluded. We evaluated the patient's complaints according to minimal, moderate, and severe discomfort and time between start and complete insertion of the 60 cm length of the sigmoidoscope. Statistical analysis was performed by an appropriate Anova test and Fisher's exact test. RESULTS: There were no differences among these four groups relative to age(5; 58.0+/-12.7, L; 64.3+/-10.0, R; 62.0+/-10.1, J; 56.0+/-12.9), gender(5; 76%, L; 70%, R; 72%, J, 83%,male ratio), degree of discomfort (mild: 42.9% (5), 50% (L), 33.3%(R), 66.7%(J), moderate: 42.9%(5), 34.6%(L),25%(R), 13.3%(J), severe: 14.3%(5), 15.4%(L), 41.7%(R), 20%(J)) and duration of insertion of the sigmoidoscope(5; 264.4 +/-192.9, L; 226.5 +/-267, R; 301.6+/-361.3, J; 202.5 +/-117.8 seconds). Also, there were no statistical significances between the two groups according to the surgeon who performed the procedure. CONCLUSION: The best position for sigmoidoscopy does not depend on the patient's position. Therefore, allowing the patient to change his position during the procedure would be the best way for an easy and comfortable sigmoidscopy.

Although malignant melanoma usually occurs after the diagnosis of vitiligo-like depigmentation, the latter is rarely followed by the former. We herein report on such a case in which recognition of the vitiligo-like depigmentation preceded diagnosing the metastatic melanoma by several months. A 56-year-old woman had first developed vitiligo-like depigmentation on the forehead, eyelids, neck and back 18 months previously and thereafter she detected a hard mass in the left axilla 2 months previously. Based on the histologic findings, the axillary mass was diagnosed as metastatic melanoma. To evaluate the primary tumor focus, thorough examinations that included PET-CT, bone scan and sigmoidoscopy were performed, but we couldn`t find any the original primary tumor. Our case suggests that the vitiligo-like depigmentation could be a sign that heralds metastatic melanoma.

Colorectal injury related to anorectal manometry is very rare and is mostly associated with previous rectal surgery. We experienced two cases of colorectal injury related to anorectal manometry in patients without a history of surgery. The anorectal manometry finding of the first patient suggested rectal hyposensitivity, and the maximum tolerable volume was measured as 350 mL. After anorectal manometry, she complained of hematochezia. Sigmoidoscopy showed a deep 5 cm ulcer with vessel exposure at the rectum. She recovered after conservative treatment. In the second case, rectal bleeding occurred while measuring the maximal tolerable rectal volume. A 2.5 cm mural defect and 4 cm mucosal defect were detected in the rectosigmoid area at sigmoidoscopy. Computed tomography showed intraperitoneal free air around the distal sigmoid colon. She improved after conservative management. We suggest that anorectal manometry be performed with great caution, even in patients without a history of surgery.

Trichuriasis is an intestinal infection of human beings caused by Trichuris trichiura, more commonly known as whipworm because of its whip-like appearance. It is characterized by the invasion of the colonic mucosa by the adult trichuris. It is prevalent throughout the world, especially in tropical areas. Diagnosis is made typically by the identification of characteristic barrel-shaped eggs in the feces, although adult worms may be seen rarely at sigmoidoscopy or colonoscopy. We report five cases of whipworm infection that was diagnosed on colonoscopic examination.

Necrotizing fasciitis usually occurs after dermal injury or through hematogenous spread. To date, few cases have been reported as necrotizing fasciitis of the thigh secondary to rectal perforation in rectal cancer patients. A 66-year-old male complained of pelvic and thigh pain and subsequently developed necrotizing fasciitis in his right thigh. Four years earlier, he had undergone a low anterior resection and radiotherapy due to of rectal cancer. An ulcerative lesion had been observed around the anastomosis site during the colonoscopy that had been performed two months earlier. Pelvic computed tomography and sigmoidoscopy showed rectal perforation and presacral abscess extending to buttock and the right posterior thigh fascia. Thus, the necrotizing fasciitis was believed to have occurred because of ulcer perforation, one of the complications of chronic radiation colitis, at the anastomosis site. When a rectal-cancer patient complains of pelvic and thigh pain, the possibility of a rectal perforation should be considered.

BACKGROUND/AIMS: Clostridium difficile is an important cause of diarrhea in hospitalized patients. C. difficile-associated diarrhea (CDAD) is usually diagnosed following a stool test for C. difficile cytotoxin or stool culture for the presence of toxigenic C. difficile. However, the reported sensitivities of these tests are variable. Sigmoidoscopy may be an effective diagnostic method in patients with a false-negative stool test for cytotoxin. This study examined the role of flexible sigmoidoscopy in the diagnosis of CDAD. METHODS: Among the patients who had diarrhea and were examined with sigmoidoscopy in Eulji University Hospital between January 2005 and July 2008, 102 patients suspected of having antibiotic-associated diarrhea (AAD) based on their clinical symptoms were enrolled. Of the 102 patients, 74 were diagnosed with CDAD based on C. difficile cytotoxin or sigmoidoscopic findings of pseudomembranous colitis. The medical records of these 74 patients were reviewed retrospectively. RESULTS: Of the 74 patients, sigmoidoscopic findings revealed a pseudomembrane in 63 patients (85.1%) and colitis in nine (12.2%), while two patients (2.7%) appeared normal. Of the 63 patients with pseudomembranous colitis at sigmoidoscopy, the stool C. difficile cytotoxin assay was negative in 27 (42.9%). CONCLUSIONS: Flexible sigmoidoscopy was highly sensitive in pseudomembranous colitis and is useful in diagnosing patients with a delayed or negative stool test for C. difficile cytotoxin. Therefore, we recommend flexible sigmoidoscopy in patients suspected of having C. difficile-associated diarrhea for the diagnosis of CDAD.

8.Diagnosis of Clostridium difficile-associated diarrhea.
Korean Journal of Medicine 2010;78(3):316-317
Clostridium difficile-associated diarrhea (CDAD) has been one of common nosocomial infections associated with previous antibiotic use. Early diagnosis and adequate management of CDAD is necessary especially for severe cases, however, diagnosis has not been satisfactory. Cytotoxicity assay or toxigenic culture can be considered as a golden standard for diagnosis of CDAD, however, they are labor intensive and require a long time. Instead, a rapid enzyme immunoassay for toxin A and B has been widely utilized in most clinical laboratories. However, its low sensitivity has also been a limitation. Sigmoidoscopy can be helpful in a rapid diagnosis of CDAD for some cases which show negative results in enzyme immunoassay.

Intussusception most commonly occurs in children, and in more than 90% of cases, no cause is found. In contrast, intussusception in adults is relatively rare but over 90% of patients have an organic lesion as the cause. Only 5% of cases of intussusception occur in adults and most involve the small intestine and are benign, whereas colonic intussusceptions are usually malignant. We report here a case of a 70-year-old man with intussusception who was referred with a one-day history of hematochezia and abdominal pain. The intussusception was caused by a sigmoid colonic tumor. The CT findings suggested that we could reasonably proceed to a sigmoidoscopy to confirm the site of obstruction. We speculated that the sigmoid colon tumor induced the anterograde intussusception. As with our patient, it is important to recognize the need to diagnose the primary lesion exactly and promptly.

BACKGROUND/AIMS: Although multiple treatment options exist for the management of sigmoid colon volvulus, no study has examined the factors associated with successful endoscopic detorsion. This study aimed to examine the clinical course of patients with sigmoid colon volvulus and to identify factors related to successful endoscopic detorsion. METHODS: This study included 30 cases (21 patients) of sigmoid volvulus from among 545 cases of intestinal obstruction at a single center. We retrospectively examined the clinical course and the factors associated with the possibility of endoscopic detorsion of sigmoid colon volvulus. RESULTS: The rate of laxative use among the study participants was 76.2%; the rate of comorbid neuropsychiatric disorders was 61.9%; and 57.1% of patients had a history of open abdominal surgery. All patients were initially treated with endoscopic detorsion, and this procedure had a 61.9% success rate. The recurrence rate after detorsion was as high as 46.2%, but detorsion during revision endoscopy was possible in all cases. Statistical analysis revealed that the absence of abdominal tenderness (P=0.027), the use of laxatives (P=0.027), and a history of open abdominal surgery (P=0.032) were factors predictive of successful endoscopic detorsion. CONCLUSIONS: The results of our study are consistent with previous reports with respect to the success rate of endoscopic detorsion, the subsequent recurrence rate, and the proportion of patients requiring surgical treatment. In addition, we identified the absence of abdominal tenderness, the use of laxatives, and history of open abdominal surgery as factors predicting successful endoscopic detorsion of sigmoid colon volvulus.
